Is This Domain-Level or Page-Level Harmonic Centrality?
This calculator reports domain-level harmonic centrality. A graph node represents a registrable domain, not an individual URL or page. Common Crawl also publishes host-level graphs, which use hostnames as nodes.
A page-level score would require a graph where each node is a page URL, plus page-to-page edges and a centrality calculation on that graph. This site’s imported domain ranks cannot answer which page within a site is most central.
Read how the domain graph is formed, or look up a domain-level score.
This answer describes the metric used by the HarmonicCentrality.org calculator. Common Crawl’s graph releases and methods can change; check the release shown with each score.
